A visible-light-responsive metal–organic framework based on titanium hexameric cluster and high conjugation system of organic linker building block termed MOF-902 was synthesized and fully characterized. The photocatalytic properties of MOF-902 were investigated in the polymerization reaction with various monomers such as methyl methacrylate (MMA), benzyl methacrylate (BMA), and styrene (St), respectively. Gel permeation chromatography (GPC) analysis results demonstrated the high performance of MOF-902 as a catalyst, affording polymer products with high molecular weight (M_n) and low polydispersity index (PDI). The photocatalytic efficiency of MOF-902 in the polymerization transformation obviously exceeds other catalysts such as MOF-901, UiO-66, UiO-66-NH₂, MIL-125(Ti), MIL-125-NH₂(Ti), and commercial P25-TiO₂.
